Laser Scanning: Improving the accuracy and efficiency of 3D printing

Laser scanning works by emitting a laser beam to a target object or surface and measuring the time it takes for the laser pulse to reflect back. These time measurements, combined with angular information, allow the scanner to calculate the highly accurate distance and direction of each point on the surface of the object. Multiple laser beams are fired rapidly from all angles to capture a dense set of 3D coordinates, which in turn build a 3D model of the object. The advantage of this process is that it......

Top 5 Heat-Resistant 3D Printing Filaments Compared

When Regular Filament Just Doesn’t Cut It You’ve 3D printed a functional bracket for a car engine bay. It fits perfectly, looks great, and then warps into a banana-shape after a week under the hood. That’s the danger of underestimating heat. If you're building automotive components, enclosures near motors, molds, or even kitchenware, using the wrong filament can lead to deformation, brittleness, or outright failure when exposed to heat. So, you already know the solution: Choosing the right heat-resist......

Flexible 3D Printing Filament Types: TPU, TPE & Soft PLA Guide

You’re probably here because rigid PLA just won’t cut it. Maybe your print needs to flex, bounce back, stretch, or just not snap in half under pressure. Whether it’s a phone case, a gasket, a soft robot joint, or some weird wearable idea, you’re now in the world of flexible 3D printing filaments. But here’s the problem: Flexible filaments like TPU, TPE, or soft PLA aren’t all the same. Some are rubbery and forgiving, others are more like bendy plastic. Some will glide through your printer like a dream......

Can You 3D Print Metal at Home? Costs & Methods

Key Takeaways Not a Single Step: Metal 3D printing at home is a multi-stage process (Printing + Debinding + Sintering). The initial "green part" is a fragile composite, not functional metal. High Hidden Costs: While metal 3d printers for home are cheap, the specialized furnaces required for sintering cost $10,000–$30,000 and carry significant safety risks. Performance Limits: DIY parts often suffer from high porosity and unpredictable 15-20% shrinkage, unlike industrial SLM/BJ which reaches 99%+ densi......

What Is LW PLA? How Lightweight PLA Works and When to Use It

The first time you print with LW PLA, you will genuinely think that you grabbed the wrong spool off the shelf. Pick the part up off the bed and it will feel hollow. But it isn't. Same infill setting, same model, just... lighter. Sometimes, depending on print temperature and expansion ratio, it can reduce part weight by approximately 20–50%. So what's actually going on? This guide walks through what LW PLA is, why it does what it does, and the settings that'll get you there without fighting the printer......
